超星阅读器中涉嫌非法使用开源图形库DjVuLibre，DjVuLibre提供了高效的图像压缩格式DjVu格式。

验证超星中包含了DjVuLibre过程很简单，首先到超星主页下载最新的超星阅读器并安装。同时下载PE Explorer的试用版。安装并启动PE Explorer，在弹出的窗口中选择File(文件)Open File(打开文件)，然后浏览你的windows目录(C:Windows)下的system32子目录下的pdg2.dll，程序会提示你是否继续，选择Continue(继续)。载入后，选择Tools(工具)菜单下的Disassembler(反汇编)，然后选择Start Now(开始)，PE Explorer会将程序转换为汇编代码，按Ctrl+F，查找djvu，你就会发现程序的汇编代码中有很多包含djvudocument类的字符串，而google一下这些含有djvu的串，你就会发现无一例外的来自开源软件Djvulibre。包含Djvu关键字的串参见附件。

超星这种无视开源软件授权的做法是对软件作者劳动的践踏。作为国内最大的电子图书制作商，在以盈利性质的软件中使用专利图像格式djvu和开源软件无疑都是非常不明智的做法，蕴含了巨大的法律风险。

有趣的是，在超星的软件下载主页上，我们又一次看到了熟悉的“自主知识产权”字样，我们曾经在一度沸沸扬扬，最后被证实为造假的“汉芯"的宣传材料中看到过，我们也曾经在花费了8000万纳税人的税收，但后来被发现大规模抄袭FreeBSD的“麒麟操作系统”的宣传材料中看到过这个名词。而非常不幸的是这次这个名词出现的地方又一次让我们失望了。

从一开始使用产生80年代产生的TIFF G4压缩格式，到后来简单更改GIF/JPEG格式后缀，到现在剽窃开源软件，使得我们一次又一次地认识到超星不但是一个没有任何技术创新能力的公司，而且商业诚信也让人怀疑。

超星中包含的GPL代码已经反馈给自由软件基金会(FSF)，我们期望国内的信息产业公司遵守游戏规则，珍重自己的诚信。
